摘要

Photoluminescence (PL) of CdS nanocrystals (NCs) grown in different polymeric matrices is investigated. It is shown that chemical nature of the matrix does not affect the nature of PL centers in NCs. PL centers of NCs are identical to the emission centers in CdS single crystals and are related to their intrinsic defects.
